VENTILATION FOR'BUILDINGS.

' Q Application tiled February 13, 1884. (No model.)

Zo all whom it may concern:

Be it knownthat I, HENRY VoLLWEILER, a resident of Brooklyn, in the county of Kings and State of New York, have invented an Improved System of Ventilation for Buildings, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in whichsystem of ventilation.

Figure 1 is a face view or inner side view of a wall in a building having my improved Fig. 2 is a, vertical cross-section of the same. Fig. 3 is a perspective view of a room which contains my system of ventilation. Fig. 4 is a horizontal section on the plane of the line c, Fig. 2. Figs. 5 and 6 aredetail face and side views of ventiings already erected.

4o joins the room.

This invention has for its object to produce a rational system of ventilation for rooms, whereby the foul air will be carried away with absolute certainty.

The invention consists, principally, in con-' necting each room, by apertures in its upper and lower parts,with a flue, which is intended to carry off the impure air, and with a small heating apparatussuch as a gas-1i ght-thdt is placed in the lower apperture to create a draft in said flue, all as hereinafter more fully described. 7

wall of a room. B isa suitable flue adjoining the wall of said room. 0 and D are two metallic boxes, which are set into the said wall A,

to line apertures which cause the interior of said room to communicate with the-flue B. The upper box, O,which is near the ceiling of the room, slopes slightly upward, and is narrower where it joins the flue than where it The lower box, D, is also made to slant upward, and is wider nearest the room. The box 0 contains agate, a, which is shown elevated by full lines in Fig; 2, but which can be swung down into the position indicated by dotted lines when ventilation is not required. The gate a is controlled by a suitable cord, 7), which passes over a frictionroller or other support in the front of the box 1 full lines in Fig. 2, and which can be raised to close the box D by a suitable cord, 0, with which it is connected. Each of these boxes .has a rotating ventilator-wheel, f, in front,

which is of suitable construction, and which,

when the air passes through the boxes into the flue,will be revolved, and willthereby indicate the fact that the ventilator is operative."

The tapering form of the boxes G and D has for its object to cause the air which passes through them to move more rapidly than it would through a box not tapered, and also to prevent, in connection with'the ascending po sition of said boxes, an air, smoke, or the like from the flue B entering the room, for the flue B may be a smoke-flue. The gates at and d can be set or adjusted in such manner as to regulate the amount of air that passes into the 'fi ue B through either of said boxes, and either gate may be shut wholly, if desired. Another advantage obtained by my arrangement is that if it is fitted into a smoke-flue above the place where the same connects with a stove, grate, or the like, the admission of the air into'the same flue will retard the combustion in the heating apparatus, and will cause considerable economy in fuel and more perfect combustion;

but if the flue B does not connect 'with the heating apparatus, it will be desirable to asp sist the air in its motion to and through the In the drawings, the letter A represents thethe wall A, which aperture can be regulated by'a suitable register, G, in front. Through this register G the air enters the aperture F, and is heated by the flame of the burner E, and then passes with the products of combustion into the flue B, warming the air therein to such an extent as to insure its ascent and the consequent current, which is desired to be produced in order to make the ventilating apparatus operative; but this little heater E is only to be used in case the disks f f indicate that a current of air does not pass from the room into the flue, or that it does not pass with the proper speed, in which case by lighting theburner E, such assistance will be given to the other part of the mechanism as will in sure the production of the proper air-currents in the requisite direction.

It will be perceived that when my apparatus is provided with this heater E a room can be ventilated with certainty and thoroughness, without producing disagreeable drafts, without overheating the room, and in a noise less manner. An additional advantage is that regulation of the air-currents can at all times be effected. The system can be placed in frame buildings as well as in those made of brick or stone. The flue 13 may be built up of sheet-metal pipes, or it may be wholly built up of brick or stone.

Of course to buildings yet to be erected this invention is most conveniently applicable.

Fig. 3 shows also a means of introducing fresh air intoarooln thus ventilated. For this purpose I place abox, H, of sheet metal or the like, between the floor-beams of the room, and lead this box into a vertiealflne,1,which communicates with the room through a suitable register. Fresh air is supplied to the box II from the outside by suitable connection. The register 9 of the air-flue I should preferably be near the ceiling of the room, so that the fresh air which enters through this registerwill be mixed withv the heated upper stratum of air in the room, entering the latter in the same ratio and to the same extent as the foul air disappears through the flue B.

Figs. 5 and 6 show face and side views of fines that can be set into building's already constructed, for the purpose of introducing therein my improved system of ventilation. In Fig. 6 it is shown that these ilues may be used to even ventilate adjoining rooms on the same floor-that is to say, apertures, i, leadin g into the backs of these fines will carry away foul air from rooms that adjoin those which communicate with the fronts of said flucs.

I claim- 1. The combination of the wall A and flue B with the boxes 0 D, the boxes being constructed to incline upward, and being narrower on the inner than on the outer sides, substantially as herein shown and described.

2. The combination of the wall A, box (3, and line B with the gatea and indicator-wheel f, substantially as herein shown and described.

3. lhe combination of the wall A and flue B, said wall having one or more passages that lead into said flue, with the air-heater E and indicator-wheels f f, substantially as and for the purpose herein shown and described.
